Perfect matched & balanced pair of vintage Telefunken ECC88/6DJ8 Audio Tubes - Special Edition - Berlin, 1959 - NOS Tubes Summary Manufactured in 1959 for industrial use and stamped with the special blue and green birthmarks on top, these are probably the most colorful Telefunken tubes we have ever seen. But wait until you hear the sonic differences these special marks make: extra Telefunken precision, extra Telefunken clarity, extra Telefunken low noise, extra Telefunken gripping...all the greatest traits of the Crown Jewelry ECC88/6DJ8 tube times two is what you get from this ultra rare pair. Sound Qualities Like any other Telefunken tubes, they are pleasant to listen to, liquid, euphonic, with a slightly warmer midrange, which makes your sound experience smooth and non-fatiguing, and all that happens on a unbelievably realistic holographic sound stage. Sound texture can be felt through infinite levels of details, laying on top of each other, both in depth and in width. Ones quest for superb sound clarity can end right here. Aforementioned in the summary section, these industrial tubes provides ultra precision in signal amplification, which helps bring in haunting realism to the famed Telefunken holographic sound stage - if you mistaken something in the sound for your next door neighbor please dont blame these tubes! Professional Sound Evaluation The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring. - Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC - Amplification: Liquid Platinum Tube Amplifier by Alex Cavalli - Output: Focal Clear MG Pro open-back headphones Our full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above. Professional Tube Testing Both tubes tested NOS (100%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in both uMhos and percentage relative to nominal for your convenience): Tube 1: 13,200/13,700 (106%/109%)Tube 2: 13,000/13,000 (104%/104%) Good tubes start at 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and the Mercury 2000s rated mutual conductance (nominal) for new tubes is 12,500. Test result can also be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, its actually quite straightforward: mutual conductance directly translates to a tubes ability to amplify sound, so the higher the numbers the stronger. Appearance & Cosmetic condition Beside the fantastic sound signature, we treasure this pair also because the great condition of inscriptions on the tubes. The Telefunken logo is visible on both tubes and one of them has nearly perfect paint and of course the Berlin date codes on the side: B rc 05 (B = Berlin, rc = Feburary, 1959.) And of course the diamond mark on bottom - the symbol of the best sound one can ever find on ECC88s. Shipping Policy - Ship worldwide!
